D. Polycarpellary syncarpous.

Answer

### Step-by-Step Solution:

1. **Understanding Gynoecium**:
- The gynoecium is the female reproductive part of a flower. It consists of one or more carpels, which are the structures that develop into fruit after fertilization.

2. **Identifying the Family**:
- The question pertains to the Solanaceae family, which includes many economically important plants such as tomatoes, potatoes, and eggplants.

3. **Analyzing the Options**:
- The options given are:
a) Monocarpillary
b) Bicarpillary apocarpus
c) Bicarpillary syncarpus
d) Polycarpillary syncarpus

4. **Determining the Structure of Gynoecium in Solanaceae**:
- In the Solanaceae family, the gynoecium is characterized as **bicarpillary**, meaning it has two carpels.
- Additionally, the carpels in Solanaceae are **syncarpus**, which means they are united or fused together.

5. **Evaluating the Options**:
- Option a (Monocarpillary) is incorrect because Solanaceae has two carpels.
- Option b (Bicarpillary apocarpus) is incorrect because apocarpus refers to separate carpels, which is not the case here.
- Option c (Bicarpillary syncarpus) is correct as it accurately describes the gynoecium of Solanaceae.
- Option d (Polycarpillary syncarpus) is incorrect because it suggests more than two carpels.

6. **Conclusion**:
- The correct answer is **option c: Bicarpillary syncarpus**.
